Introduction of new indices to identify relative drought tolerance and resistance in wheat genotypes

Cloning and characterization of endo-β-1,4-glucanase genes in the common wheat line three pistils

In this work, we report the cloning and characterization of endo-β-1,4-glucanase (EGase) genes (TaEG) in the common wheat line three pistils. Three TaEG homoeologous genes (TaEG-4A, TaEG-4B and TaEG-4D) were isolated and found to be located on chromosomes 4AL, 4BS and 4DS, respectively. The three genes showed high conservation of their coding nucleotide sequences and 3 untranslated region. The ...

The differences in intestinal viscosity produced by barley and beta-glucanase alter digesta enzyme activities and ileal nutrient digestibilities more in broiler chicks than in cocks.

The objectives of this study were to determine whether intestinal viscosity caused by mixed linked barley beta-glucan depresses ileal nutrient digestibility and digestive enzyme activities and to determine the interaction of intestinal viscosity, digestive enzyme activities and ileal nutrient digestibility in different ages of poultry. In Experiments 1 and 2, 1-d-old broiler chicks and 1-y-old ...
